SUMMARY OF THE INVENTION

The present invention is directed to adjustably mounted slippers having a toe enclosing portion adjustably connected to a heel engaging portion wherein moisture absorbent materials are provided only along an upper portion of the toe portion and along an inner portion of the heel engaging portion. Due to the limited and selected placement of moisture absorbent materials, moisture is only applied to areas of a person's toes around the toenails and cuticles and also to an area along a heel portion of the foot so that these selected areas of the foot are subjected to softening by absorbed moisture within the moisture absorbent materials without exposing the remainder of the foot to moisture. Thus, the slippers may be used to soften toenails, cuticles and calluses while maintaining the remainder of a person's foot dry and at a comfortable temperature.

The slippers of the present invention are used to enhance pedicure procedures by allowing only selected portions of a person's foot to be subjected to moisture treatment to soften toenails, cuticles and heel calluses while the remaining portions of the person's foot remain dry. The slippers include an enclosed toe portion forming a cavity for receiving a front portion of a person's foot so that all toes are completely housed with the cavity when the slippers are worn. The sole of the toe portion is constructed of a nonabsorbent closed foam neoprene material enclosed between a nylon tricot inner covering and a bottom textured rubber gripping surface material.

The upper of the toe portion is formed of a nonabsorbent closed foam neoprene material covered by an outer nylon tricot material and an inner fleece or other soft and absorbent inner material that has been treated with anti-microbial and anti-bacterial agents. The upper edge of the upper of the toe portion is seemed with a soft fleece decorative seem or cap to provide comfort across the top of a person's foot when the slipper is being worn. The upper and sole are secured along their edges by a waterproof hem that is sewn around a perimeter of the toe portion of the slipper. The hem retains the moisture within the upper absorbent material of the toe cavity.

The slippers of the invention also have a heel engaging portion or pad that is adjustably mounted relative to the toe portion by at least one adjustable elastic strap that is sewn to the upper and opposite side portions of the upper so as to be secured to the toe portion without interfering with the toe enclosing cavity. The heel engaging portion or pad includes an inner nonabsorbent neoprene closed cell foam material that is covered with a fleece material moisture absorbent inner liner that is engaged with the heel of a person's foot when the slippers are worn. This fleece material is designed to apply moisture to the area of the person's heel to soften calluses in the area of the heel. The nonabsorbent inner material of the pad may be covered with a nylon tricot material. In order to make the heel pad adjustable relative to the elastic mounting strap connecting the heel pad to the toe portion of the slippers, another outer nonabsorbent material is attached to the pad by securing along the upper, lower and side edges of the heel pad. Two pair of reinforced slits are made in spaced relationship to each other in the outer nonabsorbent material to thereby create a pair of spaced belt loops through which the mounting strap extends.

To further stabilize the heel pad to a person's foot, the heel pad has outer and upwardly oriented side or wing portions. A resilient ankle engaging strap is secured to one of the wing portions and a first hook and loop engaging material is secured to an outer end of the ankle strap. A second hook and loop engaging material is secured along an end portion of the other wing portion for cooperatively engaging with the first hook and loop material to secure the strap about the person's ankle when the slipper is being worn.

It is an object of the invention to provide a slipper for preparing a person's feet for pedicure and callus treatment wherein the slipper applies moisture to only those areas of a person's foot that are to be treated and in this respect provides moisture absorbing materials only in areas of the upper of a toe enclosing portion of the slipper which are in contact with the toenails and cuticles of the toes and with heel engaging areas of a heel engaging portion of the slipper.

It is yet another object of the invention to provide slippers for use in softening toenails, cuticles and calluses of person's feet by adjustably securing toe enclosing and heel engaging portions of the slippers to areas of a person's toes and heel.

It is a further object of the invention to provide a method of selectively treating only certain portions of a person's feet with moisture to facilitate a pedicure so that other portions of the person's feet are not exposed to unnecessary moisture and wherein the structure of the slipper creates a “wet suit” effect in the moisture absorbent areas of the slipper to make a temperature of the slippers in such areas more comfortable.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With continued reference to the drawings, a slipper 10 of the present invention is shown in FIGS. 1-6 for use to enhance pedicure procedures by only applying moisture or soaking selected portions of a person foot in preparation for treatment of the toenails and cuticles and heel calluses of the foot. The slipper includes a toe enclosing front portion 12 which is connected to a rear heel engaging portion or pad 14 by way of a at least one resilient strap 15, which may be adjustable. The toe enclosing front portion includes an opening 16, see FIGS. 1 and 4, for receiving a front portion of a person's foot from adjacent the ball of the foot to the end of the toes.

With specific reference to FIGS. 5 and 9, the structure of the slipper will be described in more specific detail. The structure is important as the object of the slipper is to only apply moisture to specific areas of the foot in preparation for a pedicure procedure. As shown, the sole portion 18 of the toe enclosing portion front portion 12 of the slipper is constructed of a cushioning material which, in the preferred embodiment, is a nonabsorbent closed foam neoprene material 20 enclosed between a nylon tricot inner covering 21 and a bottom rubber or rubber-like traction layer 22. Preferably, the bottom surface of the rubber or rubber-like layer 22 is textured to provide a non-skid gripping surface for the slipper. The sole portion is generally soft and flexible or pliable to facilitate wearer comfort and is specifically constructed so as to not absorb liquids such that the bottom of a person's foot is not exposed to moisture when the slipper is worn.

With reference to FIGS. 6 and 8, the upper 24 of the toe enclosing front portion 12 of the slipper is formed of a cushioning material which, in the preferred embodiment, is a nonabsorbent closed foam neoprene material 25 covered by an outer and upper nylon tricot material layer 26 and an inner fleece or other soft and liquid absorbent inner material 28 that has been treated with anti-microbial and anti-bacterial agents. An upper edge of the upper of the toe enclosing front portion is provided with a soft fleece decorative seem or hem 30 to provide comfort across the top of a person's foot at the opening 16 when the slipper is being worn. The upper and sole are secured along their edges by a waterproof hem 32 that is sewn around a perimeter of the toe enclosing front portion 12 of the slipper. The hem 32 retains the moisture within the upper absorbent material of the toe cavity. When in use, water, ointments, lotions and other skin softening or medicinal liquids may be absorbed within the absorbent inner material before the slipper is applied to a person's foot so that the moisture is directed to the area of a person's toenails and cuticles. The upper 24 is generally soft and pliable and thus comfortable to a person's foot.

From the foregoing, moisture is only applied to limited areas of a person's foot to enhance pedicure treatment of in area of the toenails and cuticles and such that the sole of the person's foot is not in direct contact with any moisture and thus remains dry when the slipper is worn.

The at least one adjustable and resilient strap 15 is connected at opposite ends 33 and 34 thereof to the upper 24 just above the sole portion 18 by being secured between the soft seem 32 and two patches of covering material 35 which may be a vinyl. In the preferred embodiment shown, the ends of the straps are sewn between the other materials. The strap is resilient such that the strap provides a force to draw the heel engaging portion 14 continuously toward the toe enclosing front portion 12 of the slipper. In use, after a person place their foot with the toe enclosing front portion, they can pull the heel engaging portion away from the front portion until the heel engaging portion can be placed to the rear of the heel such that moisture carried by the heel engaging portion may be placed into contact with calluses on the heel.

To further permit additional adjustment to the strap 15 and as shown in FIGS. 1 and 3, in some embodiments, one of the ends 33 of the strap may be connected to a slide member 37 after passing through a ring 38 formed of plastic or metal to which a secondary strap segment 39 is secured. The secondary strap segment is sewn or otherwise secured to a side of the upper just above the sole portion 18 between the soft seem 32 and the patch covering material 35. The end of the strap terminates in a closed loop about a center post 40 of the slide member 37 having parallel openings 41 therein, see FIGS. 3 and 6, through which the strap 15 extends. By sliding the slide member closer to the ring 38 the length of the strap is maximized whereas by moving the slide member toward the heel engaging portion 14 of the slipper the strap is shortened to position the heel engaging portion 14 closer to the toe enclosing front portion 12 of the slipper.

With reference to FIGS. 2-4 and 10, the heel engaging pad 14 includes a central portion 43 that includes an inner cushioning material, which in the preferred embodiment, is a nonabsorbent neoprene closed cell foam material 44 that is covered with a fleece material moisture absorbent inner layer 45 that is engaged with the heel of a person's foot when the slipper is worn. This fleece material is designed to apply moisture to the area of the person's heel to soften calluses in the area of the heel. In order to make the heel pad adjustable relative to the elastic mounting strap connecting the heel pad to the toe portion of the slipper, another outer nonabsorbent material, such as a vinyl material layer 48, is attached to theeel engaging pad 14 by securing along the upper and lower edges and side edges of the pad such as by stitching. Two pair of reinforce slits 49 are made in spaced relationship to each other in the outer nonabsorbent material to thereby create a pair of spaced belt loops 50 through which the strap 15 extends.

To further stabilize the heel pad to a person's foot, the heel engaging portion or pad 14 has outer and upwardly oriented side or wing portions 51 and 52 that extend from the central portion 43. A resilient ankle engaging strap 54 is secured to the wing portion 51 and a first hook and loop engaging material 55 is secured to an outer free end 56 of the strap, see FIG. 7. A second hook and loop engaging material 57 is secured along an outer portion of the other wing portion 52 for cooperatively engaging with the first hook and loop material to secure the ankle engaging strap 54 about the person's ankle when the slipper is being worn.

In use of the slipper 10, a liquid such as water, ointments, lotions and other skin softening or medicinal liquids is introduced into the cavity of the toe enclosing portion 12 such that the liquid is absorbed within the absorbent inner fleece material 28, without collecting or pooling within the toe enclosing portion. The liquid is also applied to the fleece layer 45 of the heeling engaging pad. After the absorbent layer have been moistened, the slipper is applied to a person's foot such that the toes and front portion of the foot enter the toe enclosing portion 12 so that the moisture is directed to the area of a person's toenails and cuticles. The upper 24 is generally soft and pliable and thus comfortable to a person's foot. Thereafter, the heel engaging pad 14 is placed around the back of the person's heel so that the moisture absorbing layer 45 contacts any calluses on the back of the heel.

is With reference to FIG. 7, the adjustment means for the strap 15′ may be placed on an opposite side of the slipper 10′. Thus the ring 38′ and slide member 37′ are provided adjacent the wing portion 52′ of the heel engaging portion or pad 14′ as opposed to the wing portion 51. Also, although not shown in the drawings, the ankle engaging strap may be mounted to the wing portion 52 of the heel engaging pad such that the free end of the strap with the hook and loop material is locked to hook and loop material provided on the other wing portion 51 of the heel engaging portion or pad. Further, the slipper may be manufactured in pairs designed to be more complementary to left and right foot configurations such that the front toe enclosing portions of the slippers are curved slightly to the left or the right, respectively.
